Why Doesn’t Evaporated Milk Go Bad Quickly? Understanding Its Shelf Life
Learn why evaporated milk lasts long, how high-temperature processing and reduced water content preserve it, and proper storage tips after opening.
Video transcript
Evaporated milk doesn't go bad quickly due to its high-temperature processing. The milk is heated to remove about 60% of its water content, which kills bacteria and increases shelf life. Additionally, the reduced water content and canning help preserve it, making it safe for long-term storage. However, once opened, it should be refrigerated and used within a few days.
